Outline: BONE FORMATION = (osteogenesis) begins during prenatal development and continues through adulthood.

• A bodies bone is softer because it has yet to ossify, the process of synthesizing cartilage into bone.
• 2 Ways to have osteogenesis occur. Intra membrous ossification this form mostly uses the cell called an osteoclast
• Specialized cells in bone tissues that deposit calcium into the bone matrix (collagen).
• Osteoclast - are the specialized cell that dissolve calcium previously stored away in bone and carry it to tissues whenever needed.
• One third of all the bones components is collagen
• Collagen = A flexible gelatin like matrix.

Intramembranous Ossification:

• As seen under a microscope, membranous bones first appear as flat, membrane-like layers of early connective tissues.
• Osteoblast are formed and remove calcium from the blood system and then apply it to the matrix.
• Osteoblast cover a spongy bone layer in a harder ossified layer that then turns the osteoblast into osteoclast.
• The old osteoblast come back up and add another spongy layer and continue to add harder bone layers.
• This process is slow and time consuming.
